I didn't know Consumer Reports' views on nitrogen. Now, it really doesn't make a difference for me in my nitrogen preference. I know CR rates COSTCO very highly as a large retailer for good pricing and customer service.
Consumer Reports bottom line, fwiw.
The average loss of air-filled tires was just 3.5 psi from the initial 30 pressure setting. Nitrogen-filled tires lost an average of 2.2 psi from the initial 30 psi setting. More important, all tires lost air pressure regardless of the inflation medium, so consumers should check their tires' air pressure routinely. No evaluation was done to assess the aging claim.
Bottom line: Overall, consumers can use nitrogen and might enjoy the slight improvement in air retention provided, but it's not a substitute for regular inflation checks.
